ing Doors Closing Lift or Stairway Openings in Floors of Buildings, ofwhich the following is a specification.

This invention has been patented to me in Great Britain October 1, 1890,No. 15,541; in Belgium October 1, 1890, No. 92,171; in Austria-HungaryFebruary 12, 1891, No. 44,193 and No. 77,829; in Turkey October 1,1890,N0. 196; in France October 1, 1890,No. 208,578; in Italy November 13,1890, Vol. LVI, 82; in Spain November 15, 1890, No. 11,291; in Bra zilDecember 16, 1890, No. 1,018, and in Cape of Good Hope February 4, 1891,No. 666.

This invention is specially adapted for opening and closingsimultaneously lift or stairway openings in lofty buildings by means ofhinged or folding doors. This is effected by means of a vertical shaftplaced parallel to but outside the lift or stairways and running fromthe top to the bottom of the building. The shaft is provided on eachfloor with a hand-wheel, by means of which the shaft may be rotated fromany floor. A bevel-pinion is keyed onto the shaft at each floor, eachbevel-pinion gearing with abevelwheel on a transverse shaft, from whichmotion is communicated to the hinged door.

In the accompanying drawings, Figure 1 is a sectional side elevation ofastairway-opening operated indirectly from a transverse shaft by meansof winding-gear. Fig. 2 is a partial end elevation of the same.

A is a vertical hand-shaft continued from floor to floor throughout theheight of abuildlng.

B B are the hand-wheels whereby the shaft A may be operated from anyfloor.

O is a bevel-pinion keyed on the shaft A and gearing with thebevel-wheel C, placed on the end of a transverse shaft D.

The transverse shaft D carries windingdrums G G, provided with ropes gg, the opposite ends of which are made fast to the upper side of thedoors E. When the vertical shaft A is rotated, motion isimparted throughthe bevel -gearing O O to the transverse shaft D and winding-drums G G,and the door will consequently be raised by the ropes g g to theposition shown by dotted lines in Fig. 1. It will be manifest that whenthe vertical shaft A is rotated from any fioor by any hand-wheel B thewhole of the doors connected therewith will be simultaneously opened orclosed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is

In combination, the hatchway-door hinged at oneedge, a shaft journaledabove the door and extending parallel with the free edge of the same,the two drums, oneiat each end of the said shaft, the flexibleconnections from the drums to the free edge of the door near REUBENHALLENSTEIN.
